Our reprinted booksare derivative works based on original texts long out of print
and now in the public domain (which means that at least seventy years has elapsed
since the author’s death, and copyright has expired). All are books of historical
and cultural importance from the Victorian period and the early twentieth century.
The subjects are mainly in the fields of Science, Technology, Engineering and Mathematics
(STEM) of a bygone era.

However, our books are NOT slavish copies of the books printed long ago by long defunct
publishers. All are newly typeset in modern, easily readable typefaces. Our aim is
provide a prime reading experience, not to produce books which in essence are fakes,
attempting to look “old”. Many such can be found in online book stores, usually reproduced
by OCR scanning, which are never proof-read, contain innumerable errors and are not
worth their asking price. Beware!

Instead, our reprints are truly New Editions, with attractive specially designed
covers for each book (OCR scanned books usually have a single nondescript cover design
for every book offered by individual producers - again, beware!) We do not, of course,
omit a single word of the author’s text, or a single illustration, figure or table
found in the original. But we do more, we add some content. We usually include a
short biography of the author, together with notes about the book’s history, and
we often provide explanations of an author’s contemporary references, if they have
long since passed out of memory.

We carefully edit the text, for example we might break up long passages into shorter
and more readable paragraphs. Sometimes we break text up into separate chapters,
where such divisions are lacking in the original. Pagination is not the same as the
original, but is designed to suit the new edition. Tables of Contents and Lists of
Figures are updated to reflect the new pagination. If such are absent in the original
publication, then we provide them. Captions to illustrations are either reproduced
or added if not otherwise present.

Finally, before publication, our books are proof-read by at least two readers, in
an attempt to remove any errors which may have crept in unnoticed during print preparation.
Enjoy!
